UNITED a BAG-CLEANING MIACHINE.

.Application filed January 6, 1921. Serial No. 435,529.

To allwhomz't may concern: a

Be it known that I, HENRY J. F. T. KAoKnR, a citizen of the United States of f America, residing at Birmingham, in the- 5 county of Jefferson and State of Alabama,

have invented certain new and useful Improvements in Bag-Cleaning Machines, of which the following is a specification.

This invention relates to a bag cleaning machine of'the type comprising aslatted rotating drum'into whichthe bags to be cleaned are introduced and which is rotated with internal elements designed to raise the bags and to cause them to drop so that the dust and dirt therein will: be beaten out against the slatted walls of the drum and .will escape therefrom. i In a device ofthis character it is of prime importance that the drum be designed to avoid tearing or excessive wearon the bags and to this end my drum. is formed with in ternal slatted shelvesof such shape as to present no sharp edges against which the sacks may fall and over which they will be drawn and which will be of such character as to avoid collecting and holding the sacks thereon after a shelf rises appreciably from its lowest level, to the end that the.

sacks may all be collected in one pocket formed between the lowermost shelves. 1

Another further feature of my invention is the provision of a bag cleaning apparatus of the type above described with a door in its peripheral walls so arranged between shelves as to permit of the most convenient removal of the bags when collected in the "pocket between such shelves, thus permitting all bags to be withdrawn at the same time,

and without having to get into the drum to clean out the pockets. p

A further object of my invention is to simplify and perfect themanner of com structing a slatted drum comprising middle rings to reinforce the longitudinal slats and to carry the intermediate supports for the internally projecting slatted shelves.v

A further object is to simplify the construction by attaching the slats to the out side periphery of the end rings carrying the end slats and to the inside peripheries of the intermediate reinforcing rings.

My invention further comprises the novel details of construction and arrangements 1 ofparts, which in their preferred embodiment only are illustrated in the accompany? I mg drawings which forma part of this specification, and in which Fig. 1 is a side elevation of my apparatus.

Fig. 2 is aha-1f end view and half cross sectional View of the drum. I

' Fig. 3 is a partial plan view of an end ring; and a I Fig. at is a partial plan view of an intermediate ring with parts of the slats shown in both views. a a i Fig. 5 is a detail view of the door latch.

I Similar reference numerals refer to similar parts throughout the drawings.

As illustrated, my invention comprises a drum of large diameter mountedona central shaft 1 which turns in bearings 2 carried by supports of any suitable character. The drum may be driven by any suitable source of power, not shown. The endsof the drum, which are alike, comprise a pair of spaced hub plates 4 and 5 which are fast on the shaft 1 and have bolted between them radial spokes 6 which extend to the periphery ofthe ends and are there received between curved spacing strips 7 (F 1g. 3), which form with the intervening spokes an annular rim, to the inside face of which is bolted a second annular ring formed of curved spacing strips 8 and interposed shelf blocks 9, the segments of the inside rim being disposed at breakjoints with the outside rimrand the parts cross connected by bolts 10 between spokes and by bolts 11 through the spokes. I show four of the shelf blocks, arranged equi-distantly about the rim and each having its edges that project towards the hub sloping at an angle of nearly 135 to the spokes. One spoke is bolted at the apex and base of each of these blocks, and for the sake of lightness the center of the block may be cut away. Thewalls of the block are thus inclined so as to rise at a gentle slope from the inner periphery of the rim for the purposes herein- 1 after described. The two skeleton end frames formed by the spokes are covered by spaced slats l2 and 1 3, the former being arranged about the outer zone of the frame and each subtending three spokes, while the inner slats 13 fill in the space between the slats 12 and the hub plates and are arranged. to connect different groups of three spokes from those which are connected by the slats 12. This arrangement of the slats 12 and 13 to. connect different groups of three spokes gives greater to'theend frames. frames are alike, the description of one appliesto both. The two endfraines are cross 5 connected by longitudinal spaced slats 14:

which extend continuously from end to end h its lowered position by means of a fastener of the drum, those which are attached to the end rims betweenthe shelf blOckshaVing their inside faces notched so that their re- IO 'duced ends 15 overlap the outside periphery of this part' ofthe rimand are attached #th'ereto.

. A i l. J F In View, of the capacity to be obtained f'rorntl 'ie drum and the lightness oi the slats,

itis desirable to provide them, with intermed ate bra ces and this I (do by the provision ,of two intermediate; lamlnated rings indii cated generally by the reference numeral: 1Q 'and each formed by an outside series of curved bars or segment plates 17 between which and at, break jointstherewith are an inner series of curved bars or segment plates 18. -To' theclatter are-attached thefourjinterniediate, shelf blocks-19; which have their inner faces lying in the same pia ne with the ""i'nnerfstlo pingi faces of the endas helf blocks 9. 1 5 These intermediate shelfblocks are'shown as. slotted, blocks slightly deeper than the 40" blocks 9 byreason ofthe fact that thein'side I diameter of the ring 16 corresponds exactly with the diameter' fofa circle with its peripherylyingin the plane of the outside edges ffpr't r n tq deede l5 flj s iint rr mg between "the shelf blocks. f The purpose i efthis.arraiigement is to enable a slat tobe {su tably attached to the inside periphery of .gfihrt qi s rings 6am t butsi ,P. r rh y bi th erdir ng h s h t t interior of the drum entirely free of any I projection ithereinto. the same time he e rin 16 whi 4 fl t re r ig t I .pes's elml eh stien en y c v y V reinforce the intermediate zone of the drum.

n the The drum is turnedzune "til this pocket is the oneinwhi'ch the door is Having thus described my invention, what I claim as newand desire to secure by Letters Patent, is t 1. A rotatable cleaning drum mounted to rotate about its longitudinal axis and having its interior wall formed by longitudinal slats mounted at intervals on inwardly projecting frames formed by hubs, spokes radiating gradually sloping substantially symmetrical spaced shelves which provide longitudinal pockets, each having a wide arcuate bottom wall and divergent gradually sloping walls, the sloping walls of each shelf being dis-n posed at an obtuse angle and meeting in a rounded top edge, and a rotatable frame work forsupporting said slats.

2. A cleaning drum comprising end walls having a run carrying inwardly projecting shelf blocks, intermediate rings of greater diameter than the end rim and having in- Wardly projecting shelf blocks with sloping faces lying in the same plane with aligning end shelf blocks, longitudinal slats extending from end to endqof the drum and attached to the outer periphery of the end rim and the inner periphery of the intermediate rings and also attached to the aligning facesv of the intermediate and end shelfblocks, and means to rotate the drum.

3. A cleaning drum comprising end walls having a rim carrying inwardly projecting shelf blocks, intermediate rings of greater diameter than the end rim and having in wardly projecting shelf blocks with sloping faces lying in the same plane with aligning end shelf blocks, longitudinal slats extending from end to end of the drum and attached to the outer periphery of the end rim and the inner periphery of theintermediate rings and also attached to the aligning faces of the intermediate and end shelf blocks, and means to rotate the drum, there being two intermediate rings and a door interposed between said rings.

4:. A sack cleaner comprising a slatted drum formed by end slatted walls having peripheral rims and internally projecting shelf blocks, intermediate rings of greater diameter than'the end rim and having inwardly projecting shelf blocks with sloping faces lying in the same plane with similar aligning end shelf blocks,'and longitudinal slats havingtheir inner faces round, which slats are attached to the inner periphery of the rings andhave their endsnotched for attachment to the outer periphery of the end rims, said slats being also attached to the outer faces of the aligning shelf blocks on the rings and end rims of the drum, a slatted door interposed in the drum periphcry, and rotatable supports for the drum.

5. A bag cleaning machine having end from the hubs, curved spacer blocks interposed between the outerends of the spokes,

and break joint plates attached to said spacer plates, part of said breaker joint plates forming inwardly projecting shelf walls and a body formed by longitudinal slats connected to the end walls and arranged to form at intervals substantially symmetria cal relatively shallow pockets, the bottom walls of which form substantial sectors of a cylinder and the side walls of which diverge 11 gradually sloping planes to form widely spaced inwardly project ng shelves rounded over their apices and having gently sloping side walls forming between them an obtuse angle.

7. A drum mounted to rotate about its longitudinal axis comprising slatted end Walls and a body formed by longitudinal slats connected to the endwalls and arranged to form four equally spaced symmetrical relatively shallow pockets, the side walls of which diverge in flat planes at a gradual slope to form inwardly projecting shelves rounded over their apiece and having gently sloping flat side walls formingbet ween them an obtuse angle adapted to, cause sacks that collect thereon to fall off by gravity from all shelves lying with their apices in or above the horizontal central plane through the drum. 1 1 A i In testimony whereof I aflix my signature.
